Life Time Warranty Made in the USA

Wire Directly Into The ECU/OBD-II (for 2008 and Newer Vehicles Only)


Aftermarket Gauge installation simplified! These gauges use the vehicle's ECU using the CAN-BUS (SAE J1979) protocol.

IMPORTANT: Freedom CAN-bus gauges will only work with OEM ECUs that are 2008 or newer and manufactured for the USA, Canada, or the UK. To use a Freedom CAN-BUS gauge you will need to know if your vehicle supports the CAN-BUS protocol and the specific gauge type data output.

  • Wires directly into the vehicle's 16-pin OBDII Data Link Connector
  • Solid Aluminum Bezel
  • Spin Lock Ring is included for easy mounting
  • Internal microprocessor controls the pointer movement
  • Digital high torque stepper motor ensures accurate pointer movement
  • Gauges are NOT waterproof

Important CAN-BUS Gauge Details (Please read before ordering):
  • Freedom CAN-BUS gauges operate by receiving data from the ECU (Engine Control Unit) through the OBDII wiring.
  • Gauges (individual or daisy chained) will not function when used in conjunction with any other OBDII device.
  • The OBDII connection does NOT provide power to the gauge.
  • Wire directly into the vehicle's 16-pin OBDII Data Link Connector (additional wiring required for gauge power and lighting).
  • Gauge CANNOT be connected to senders or anything that sends a raw signal.
For Universal Gauges, please take a look at our Revolution, Legacy, or Speedhut product lines.

More Information about Freedom CAN-BUS Gauges:

Freedom CAN-bus gauges will only work on vehicles that are 2008 or newer and manufactured for the USA, Canada, or the UK. Before you purchase a Freedom CAN-BUS gauge you will need to know if your vehicle supports the CAN protocol and your desired gauge type output. Freedom CAN-BUS gauges operate by receiving data from the ECU (Engine Control Unit) through the OBDII wiring. You can check your vehicle's ODBII connector to see if it supports the CAN protocol:

 

If the OBDII connector has wires that connect to pins '6' and '14' then the vehicle supports the CAN-BUS (J1979) protocol.*
OBDII CAN (J1979) protocol Pinout:
Pin 4 -- Chassis Ground
Pin 5 -- Signal Ground
Pin 6 -- CAN High (data)
Pin 14 -- CAN Low (data)
Pin 16 -- +12volt Battery power (not for use as gauge power)**

OBDII Connector pinout diagram
*NOTE: If there are wires connecting to pins '2' and '10' then the vehicle does NOT support the CAN protocol.
Freedom CAN-Bus gauges CANNOT be connected to a sender or anything that sends a raw signal.
**IMPORTANT: Additional wiring required for Gauge Power and Electroluminescent Dial Lighting

Typically, all vehicles 2008 and newer are required to be compatible with the CAN (J1979) protocol. Some manufacturers used the CAN protocol before 2008. Not all gauge types will be supported on your vehicle's ECU. For example, not all ECUs support fuel level output.

Check with your vehicle’s dealer or the manufacturer of the ECU for information about what types of output are supported.

The following gauges will work with all ECUs with the CAN (J1979) protocol:
  • Freedom CAN-BUS Speedometers will work with all CAN (J1979) protocol compatible ECUs.
  • Freedom CAN-BUS Tachometers will work with all CAN (J1979) protocol compatible ECUs.
  • Freedom CAN-BUS Water Temperature Gauges will work with all CAN (J1979) protocol compatible ECUs.
  • Freedom CAN-BUS Intake Air Temperature Gauges will work with all CAN (J1979) protocol compatible ECUs.
  • Freedom CAN-BUS Voltage Gauges (Voltmeter) will work with all CAN (J1979) protocol compatible ECUs.
The following gauges have limited support on ECUs with the CAN (J1979) protocol:
  • Freedom CAN-BUS Fuel Level Gauge is NOT supported on all CAN (J1979) protocol compatible ECUs.
The following gauges will only work with ECUs (with the CAN (J1979) protocol) made by General Motors (GM):
  • Freedom CAN-BUS Oil Pressure Gauges
  • Freedom CAN-BUS Oil Temperature Gauges
  • Freedom CAN-BUS Trans Temperature Gauges
